CHECK THE PCM FOR CORRECT OPERATION
1. Using a scan tool, clear the BCM CMDTCs .
2. Ignition OFF.
3. Connect: PCM C1381B (2.0L) or PCM C175B (3.5L).
4. Ignition ON.
5. Using a scan tool, perform the BCM self-test.
Was DTC C113A:11 retrieved on-demand during self-test?
- Yes: GO to 11 .
- No: For vehicles without IA, INSTALL a new PATS transceiver (vehicles without IA only). REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) TRANSCEIVER .
  For vehicles with IA, the system is operating correctly at this time. The concern may have been caused by loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
CHECK FOR CORRECT BCM OPERATION
1. Ignition OFF.
2. Disconnect and inspect all BCM connectors.
3. Repair:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
4. Reconnect the BCM connectors. Make sure they seat and latch correctly.
5. Operate the system and determine if the concern is still present.
Is the concern still present?
- Yes: CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs address this concern, INSTALL a new BCM. REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) or REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
- No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
CHECK FOR CORRECT PCM OPERATION
1. Ignition OFF.
2. Disconnect and inspect all PCM connectors.
